  Wine console applications output in the OEMCP (i.e. the DOS codepage 
for the given locale) that is usually different from the Unix console 
charset. It works if you run the program in a wine console (`wineconsole 
cmd` and run 'xcopy /?' there). I think, Wine should detect if the 
output is a Unix tty and do a conversion from OEMCP to UNIXCP, but 
that's not something that could be done before Wine 1.0.
